s rovEF'lPrin-Ameland` SPECIFICATION forming part of Letters Patent No.745,003, dated November 24, 1903.

Applicationled November 22,1902. SerialNo.132.464. (No model.)

To cir/ZZ whom, it nca/y concern:

Be it known that l, VILLIAM G. DRAKE, a citizen of the United States,residing at Donora, in the county of lVashington and State ofPennsylvania, have invented a new and useful Stovepipe-Fastener, ofwhich the following` is a specification.

This invention relates to devices for fastening stovepipes in theflue-openings of chimneys or other apertures through which the pipepasses, and has for its object to provide a simply-constructed andeasily applied and adjusted device whereby the pipe may be securelyfastened in place in position to be readily detached and adjusted to anythickness of chimney, wall, or other support; and the invention consistsin certain novel features of construction, as hereinafter shown anddescribed, and specifically pointed out in the claims.

In the drawings illustrative of the invention, in which correspondingparts in the several figures are designated by like referencecharacters, Figure 1 is a side elevation of the device applied. Fig. 2is atransverse section on the line Il Il of Fig. 1. Fig. 3 is adetachedperspective view, enlarged, of one of the leverclamps.

The improved device may be attached to any size of stovepipe and tostovepipes passing through partitions or walls or into chimneys orsupported in any other desirable manner, and for the purpose ofillustration the device is shown applied to a section of stovepipeinserted in the ordinary manner into the line-opening of a chimney, aportion of a chimney being indicated at 10 and forming a support for thepipe, a section of which is shown at 11, of the ordinary construction,the pipe being shown inserted through the usual iiueopening of thechimney.

The improved device consists in a flat relativelythin bar or plate 12,adapted to be inserted through the flue-opening between the` pipe 1l andthe flue lining or thimble and with its inner end folded over, as shownat 13, to form an offset projecting laterally from the plate or bar andthe extremity secured to the plate, as by a rivet 14, the offset 13serving as a stop to prevent the withdrawal of the' plate 12 while thepipe is in position within the line-Opening.

Attached by a handle member 15 to the free end of the bar 12 is anotherbar 16 relatively thicker than the bar 12, but preferably of the samewidth and forminga continuation thereof, as shown.

Partially embracing the pipe opposite the bar 16, preferably near itsouter or free end, are two lever members 17 1S, conforming to thecurvature ofthe pipe and extending below its center, so that theyenclasp more than one-half of the circumference of the pipe, as

indicated in Fig. 2, and forming clamp-levers adapted to be compressedinto engagement with the pipe.

The adjacent ends of the clamp-levers 17 1S are inclined inwardly andoutwardly away from the pipe 1l, as shown in- Fig. 2, and with aperturesat the j unctures of the inclined and curved portions, the aperturesadapted to receive the bent-up ends 2l 22 of the couplingrod 23, bywhich means the clamp-levers will be movably coupled and spaced apartwith reversely-inclined adjacent portions.

The inclined portions 19 2O will be formed with recesses longitudinallyof the inclined portions, as indicated in Fig. 3. The couplingrod 23Will pass beneath the relatively thick connecting-bar 16, asindicated,and is provided with upwardly-extending spaced ears or lugs23', forming guides between which the bar 16 slides and which preventthe lateral displacement of said bar, the bar being thus alwaysconnected with the levers 17 and 1 8 and held in position beneath acam-lever,here inafter described.

The clamp-levers 17 1S will preferably be formed substantially in Ushape in cross-section, the bottomportionsbeing curved to conform to theoutlines of the stovepipe and the leg portions of the U-sections formingside walls to the levers, as indicated, by which means the levers aregreatly strengthened and enabled to resist the pressure to which theywill be subjected without unduly increasing the weight or bulk. I

The pipe 11 will be surrounded with the usual collar 24 at the pointwhere it enters the flue, and connecting this collar and the leverclamps17 1S are tie-bars 25, preferably riveted by their ends, respectively,to the collar and to the clamp-levers, as indicated at 2G 27.

One of these tie-bars will be connected to each ICO of the clamp-levers,as :indicatedlin Fig. 2 upon opposite sides of the pipe.

Fittinginto the recesses in the inclined ends 19 2O of the clamp-levers17 18 are wedgeblocks 28 29, and between these wedge-blocks is pivotallysupported at 30 a cam-lever 31, the operative end 32 of the cam-leveradapted to forcibly engage the connecting-bar 1G, which passes beneaththe wedge-blocks and above the coupling-bar 23, as shown. By thisarrangement it will be obvious that when the cam-lever is moved into theposition indicated by dotted lines in Fig. 1 the clamplevers will bereleased by the depression of the wedge-blocks and the disconnection ofthe end 32 from the plate 16. If, however, the cam-lever be reversed inposition or turned, as shown in Fig. 1 in full lines, the operative end32 will forcibly compress the plate 16 upon the coupling-bar 23 and thepipe 11, while at the same time the wedge-blocks 28 29 will be forciblymoved away from the pipe and throw the outer ends of the inclinedportions 19 2O apart and correspondingly compress the longer ends of thecurved portions 17 18 forcibly against the outer surface of the pipe,and as those longer ends extend below the center of the pipe the devicewill be firmly clamped to the pipe, as will be obvious. By this simplemeans the whole device may be firmly clamped to the pipe and retain thepipe in position Arelative to the fine-opening, or other aperturethrough which it is passed, the offset 13 preventing longitudinalmovement in one direction, and the connecting-bars 25 preventinglongitudinal movement in the opposite direction, while the clamp-levers17 18 firmly engage the whole device to the pipe.

When the device is to be applied, the collar 24, with the clamp-levers17 18, coupled by the bar 23, and the wedge-blocks 28 29 and cam-lever31, connected thereto by the bars 25, will be inserted over the end ofthe pipe which is to enter the flue or pass through the wall orpartition, the connected bars 12 16 having first been placed in positionupon the pipe, with the offset end 13 extending beyond the end of thepipe. The extended portion of the bar 12, with its offset end, is thenpassed through the flue-opening or other aperture in advance of the pipeuntil the offset 13 is in position upon the opposite side of theaperture, when the pipe can be readily inserted, with the portion 12,between the pipe and the interior of the opening, the relative thi nnessof the portion 12 permitting this action. The collar 24 with itsconnected clamp-levers and attachments are then movedlongitudinally ofthe pipe, with the relatively thick portion 16 of the connecting-rodbetween the cam-lever and the pipe and preferably above the bar 23, asshown. The connected bar 12 16, which forms the connecting means betweenthe clamp-levers 17 and 18 and the pipe-support 10, is then adjustedlongitudinally of the `pipe until the offset 13 closely engages theinteriorof the fiue or other aperture and the cam-lever 31 moved intooperative position, as shown in Fig. 1, which action rmly locks theparts together, as before described. By this simple arrangement the pipemay be very quickly and readily locked in position and firmly supportedrelative to the fiue or other Vopening and all danger of thedisplacement of the pipe averted. y

The parts are all simple in construction and can be manufactured verycheaply and readily applied by persons without previous skill and willbe found very convenient and useful for the purposes described.

The parts may be modified in minor particulars without departing fromthe principle of the invention or sacrificing any of its advantages.

The clamp-levers 17 18 will preferably be of sheet metal pressed orstamped into shape, but may be constructed of other metal, if preferred.
